Queue Summary : Semester 2003A Gemini North and
South

The queue is constructed by the International TAC from the ranked
list of proposals of
each National TAC using the merging sequence
and is divided into four scientific ranking bands
(SRBs). Joint
proposals (submitted to more than one NTAC for joint support)
were combined
by the ITAC, are shown in the table as a single entry and are
executed as such. Several
proposals have multiple occurrences as they were sub-divided by the
relevant
NTAC; each component is executed separately.

Within each band, all proposals are assumed
to have equal scientific merit and have been sorted by PI name for
convenience. The choice
of which observation within which program to execute next depends on
the match to current
observing conditions, the balance of each partner's usage and other
factors such as future
accessibility, whether a program has been started etc. (see a
detailed discussion in
Puxley 1997; Gemini Preprint
#19). The aim is to exhaust band 1 (highest ranked) programs
before moving onto band 2
and so on. An observation in band 1 that does not require the best
conditions will
nevertheless be executed in preference to a band 2 observation even
if the latter is a
better match. Thus the likelihood of execution decreases from band 1
through to band 4.
Bands 1 through 3 aim to fill the nominal time available (excluding
weather loss).
Programs in band 4 overfill the queue and provide further
flexibility with respect to
weather conditions and foreseen or unforeseen problems.

In routine operation the intent is to
update this page nightly. During
shared-risks science use, this queue status page may only be updated
after each
observing block with a given instrument.

Note that individual SRBs
will not be in detailed balance with respect to partner shares.
Aggregating over two or
more bands generally provides an equitable distribution of queue
loading (in hours, not in
the number of proposals) once any classically-scheduled programs are taken into
account. Additional flexibility is available when
executing observations
to balance the partner usage of time. The intent is to achieve
balance over 2 or 3
semesters, not a single semester.

The columns in the table for Gemini
North are:Ref #: Gemini reference number (note that this is different
from any internal
National TAC reference number). Click on it to see the proposal
abstract (when
available).PI: name of Principal Investigator. (If a joint proposal, the name of the
primary contact for the entire program is listed).Partner: partner or country to which time will be charged
(US, UK, CA=Canada,
AU=Australia, AR=Argentina, BR=Brazil, UH=University of Hawaii
(host), GS=Gemini staff).
If a joint proposal, all contributors are shown.Title: the title of the program.Instrument: name of the instrument(s).Hours allocated: time allocated to the program (if a joint proposal,
this is the
total time for the program).Execution status: current status of the program (e.g. awaiting Phase II
preparation by PI, awaiting checking of Phase II science program by National
Office or Gemini staff, active in the queue [and for GMOS only, awaiting MOS
mask design], completed)Data taken: the UT date on which data
were taken [later this will include time used for each observation made]Completion status: this shows an estimate of the fraction of
allocated time that has been used. Note that this is a preliminary estimate
and is only an indication of the completion state of the program. The completion
state may not reflect the formal time accounting. Also note that some programs
may be completed in less than the allocated time (e.g. if conditions were better
than requested or if the request was overestimated).
